Public Input No. 2-NFPA 720-2015 [ Sections 1.1.2, 1.1.3 ]

Sections 1.1.2, 1.1.3

1.1.2*

This standard covers the selection, design, application, installation, location, performance, inspection,testing, and maintenance of carbon monoxide detection and warning equipment in residential buildings andstructures.

1.1.3

This standard contains requirements for the selection, installation, operation, and maintenance ofequipment that detects concentrations of carbon monoxide that could pose a life safety risk to mostoccupants in residential buildings and structures.

Statement of Problem and Substantiation for Public Input

The title for this standard should really read:NFPA® 720Standard for the Installation of"Residential"Carbon Monoxide (CO)Detection and WarningEquipment

Because it doesn't, and even though your "Origin" statement references "residential applications", many code writers may, out of habit with residential standards, specify NFPA 720 compliance for commercial CO safety standards that are currently being written. Adding the term "residential" to sections 1.1.2 and 1.1.3 is the minimum that should be done to help mitigate this potential problem.

UL 2034 listed CO alarms, and UL 2075 listed CO detectors built to UL 2034 sensitivity limits, do not comply with the OSHA CO exposure limits that are required for all commercial businesses.

This is UL's disclosure requirement for 2034 listed alarms, or 2075 listed CO detectors built to the 2034 sensitivity limits:

UL Standard for Safety for Single and Multiple Station Carbon Monoxide Alarms, UL 203484.1 Each single and multiple station carbon monoxide alarm shall be provided with installationinstructions which shall include the following information:n) The word ²WARNING² and the following or equivalent text: ² This product is intended foruse in ordinary indoor locations of family living units. It is not designed to measure compliancewith Occupational Safety and Health Administration (OSHA) commercial or industrialstandards.²

Public Input No. 23-NFPA 720-2016 [ New Section after 1.4.3 ]

TITLE OF NEW CONTENT

Type your content here ... 1.4.4 This standard shall not be used to exclude or negate responsibility for theinstallation of carbon monoxide detection and warning equipment in buildings or structures where a knownrisk of carbon monoxide exposure exists.


Currently only 12 states have any kind of legislation requiring the installation of CO detection equipment in hotels. If there is a fuel burning appliance inside a building where guests are sleeping, there should be a CO alarm system in place - regardless of whether a law exists that requires it. No facility should be allowed to use the lack or deficiency of a standard to negate their responsibility to protect the lives of those in their care.

Public Input No. 22-NFPA 720-2016 [ Section No. 5.8.5.3.1 ]

5.8.5.3.1

Carbon monoxide detectors shall be installed as specified in the manufacturer’s published instructions inaccordance with 5.8.5.3.1 (1) and 5.8.5.3.1 (2), or 5.8.5.3.1 (3):

(1)

(2)

(3) A performance-based design in accordance with 5.8.5.3.2


The current wording Section 5.8.5.3.1 (2) requires CO detectors to be installed on every habitable level and in each HVAC zone of all buildings, whether or not they are equipped with fuel-burning appliances. The current wording requires that even a building with all electric appliances and no fuel-burning appliances will require CO detectors on each habitable level and in each HVAC zone, even though there is no way for CO to be generated in the building.

Public Input No. 3-NFPA 720-2015 [ Section No. 5.8.5.3.1 ]

5.8.5.3.1

Carbon monoxide detectors shall be installed as specified in the manufacturer’s published instructions inaccordance with 5.8.5.3.1 (1) and 5.8.5.3.1 (2), or 5.8.5.3.1 (3):

(1)

(2)

(3) A performance-based design in accordance with 5.8.5.3.2

Exception: If the AHJ sees fit, it shall also be permissable to provide additional CO detection beyond therequirements of 5.8.5.3.1, installed in the airflow (Supply), before the first split of supply register of anypermanently installed fuel burning appliance(s), serving spaces which are, or can be isolated from suchlocations listed above. Spaces in which normal conscious activity is reduced and/or impaired, such assleeping areas, care areas, etc., are to be considered high potential risk for CO exposure


Rationale: The original statement does not adequately protect against CO related incidents from HVAC generated CO – Especially in sleeping areas, areas where doors are closed, and “air tight” compartments exist or could exist, Adding the proposed exception would help to help mitigate the effects of CO from a fuel-burning appliance (furnace) in these areas.

(2) On every occupiable level of a dwelling unit, including basements, excluding attics and crawl spaces

(3) Other locations where required by applicable laws, codes, or standards

Exception: The above (1) shall not be required, where the HVAC system is the only fuel burning appliancein the dwelling, and the area's supply air is monitored for CO and sebsequent notification and mitigationmeasures are employed.


Rationale: This clause does not adequately protect against CO related incidents from HVAC generated CO - Especially in sleeping areas, areas where doors are closed, and "air tight" compartments. The original clauses would typically require installation in a hallway, which many are not immediately supplied by registers from the HVAC appliance.

9.5.1.2

For electrically powered carbon monoxide warning equipment, the primary (main) power source shall be acalong with a secondary power source meeting the specifications of 9.5.4, unless otherwise permitted by thefollowing:

(1) Detectors and alarms shall be permitted to be powered by a monitored dc circuit of a control unit whenpower for the control unit meets the requirements of Section 9.5.1.3 and the circuit remains operableupon loss of primary (main) ac power.

(2) A detector and a wireless transmitter that serves only that detector shall be permitted to be poweredfrom a monitored battery primary (main) source where part of a listed, monitored, low-power radio(wireless) system.

(3) In existing construction, a monitored battery primary (main) power source, as described in 9.5.3, shallbe permitted.

9.5.1.3 Power for Household Carbon Monoxide Detection Systems shall comply with the followingrequirements:

(1) Household fire alarm systems shall have two independent power sources consisting of a primarysource that uses commercial light and power and a secondary source that consists of a rechargeablebattery.

(2) The primary source shall meet 9.5.2.

(3) The secondary source shall be capable of operating the system for at least 24 hours in thenormal condition, followed by 12 hours of alarm.

(4) After the initial 4 minutes of alarm, the 5-second "off" time of the alarm signal shall be permittedto be changed to 60 seocnds /- 10 percent.

(5) The secondary power source shall be supervised and shall cause a distinctive audible and visibletrouble signal upon removal or disconnection of a battery or a low-battery condition.

(6) A rechargeable battery used as a secondary power source shall meet the following criteria:

(a) Be automatically recharged by an ac circuit of the commercial light and power source

(b) Be recharged within 48 hours

(c) Provide a distinctive audible trouble signal before the battery is incapable of operating thedevice(s) for alarm purposes

(7) Low-power wireless systems shall comply with the performance criteria of Section 9.6.9.


The current requirements for secondary (standby) power supply in clause 9.5.4 do not distinguish between carbon monoxide detectors/ alarms applications and Household Carbon Monoxide Detection System applications. The current requirement in 9.5.4 applies to household carbon monoxide systems because clause 9.5.1.2(1) indicates the control unit needs to meet the requirements of 9.5. The requirement to maintain 24 hours of standby, followed by not less than 12 hours of alarm, followed by 7 consecutive days of trouble signal is reasonable and expected for a carbon monoxide detector not connected per 9.5.1.2(1) or a carbon monoxide alarm. The requirement for the 7 days of trouble as applied to a Household Carbon Monoxide Detection System (control unit) is not required for carbon monoxide protected premise systems (control units) in clause 4.5.6.2.3 and for comparable Household Fire Detection Systems (control units) in Chapter 29 of NFPA 72. The 7 day trouble signal requirement for the rechargeable secondary (standby) batteries of a household control unit could require an 8 fold increase in the standby battery capacity from household fire alarm control unit applications to maintain standby current to meet the additional 7 day trouble requirement.

The revision is based upon similar requirements for household fire alarm control units in clause 29.6.2 of NFPA 72.

The need for this requirement is unclear. A similar requirement is not found in NFPA 72 for smoke alarms.Upon incorporation, the language in NFPA 72 29.63(5) "alarms powered by branch circuits protected by arc-fault circuit-interrupters (AFCI) or GFCI circuit breakers shall have a secondary power source" would require battery backup for GFCI protected alarms. It is intended that the current 720 committee provide feedback on this proposed deletion for action by SIG-HOU.

A.5.3.2

Nonrequired carbon monoxide detection systems and components are those that are not required bybuilding or fire codes and are installed voluntarily by a building owner to meet site-specific safety objectives.There is a need to properly document the nonrequired system and components. Nonrequired componentsmust be operationally compatible in harmony with other required components and should not be detrimentalto the overall system performance. It is for this reason that 5.3.2.1 mandates that nonrequired (voluntary)systems and components meet the applicable installation, testing, and maintenance requirements of thisstandard. These non-required detection systems have the potential to exceed the requirement of thecurrent code, and may be used in conjunction with or in liew of the current requirements.


Rational: The addition of the new wording allows for an AHJ, if he/she deems appropriate, the ability to implement measures that exceed the current code are permissible to increase levels of life safety.

Public Input No. 6-NFPA 720-2015 [ Section No. A.5.8.5.3.1(1) ]

A.5.8.5.3.1(1)

Detectors are located on the ceiling above permanently installed fuel-burning appliances because of thebuoyancy of the heated combustion gases as compared to normal ambient temperatures. Detectors shouldbe located as close as practical to the permanently installed fuel-burning appliance consistent withconsiderations of detector accessibility, sources of detector contamination, and nuisance sources. Sitingconsiderations can include transient backdrafting spillage of flue gases during startup and ventilation supplyor exhaust vents. The principals of designed operation of the appliance should also be considered. Forexample, CO leakage will tend to be conducted away from combustion areas by design. This isaggravated when a furnace appliance is running and thusly efficiently delivering the conditioned COenriched air to other areas of the dwelling.


The current statement does not adequately protect against common issues that occur frequently to HVAC systems. Bad heat exchangers, bad or blocked air intake, bad combustion adjustment, bad or blocked vent/exhaust , etc. have all been proven multiple times each year , throughout the media and research studies, to incapacitate or even kill individuals and their families while they sleep in closed smaller spaces, such as bedrooms, hotel guest rooms, dormitories, etc. By placing or requiring for CO detection the installation outside of the airflow, there is a high potential that notification may be delayed, or not made at all, since these are often closed systems, where exposure of CO is immediately drawn back and recirculated through the system.

A.5.8.5.3.1(2)

The purpose of detectors centrally located on every habitable level is to detect the migration of carbonmonoxide from permanently installed fuel-burning appliances and other sources of carbon monoxide. Othersources of carbon monoxide can include vehicles or other equipment that uses an internal combustionengine, barbecue grills, propane-operated equipment, and systems used to generate hydrogen. Detectorlocation and spacing should be based on an engineering evaluation that considers potential sources andmigration of carbon monoxide. HVAC systems should be considered in the locating of carbon monoxidedetectors because the HVAC systems provide a good means of mixing and the migration of carbonmonoxide, yet they need to be considered as well as a potential lethal producer of carbon monoxide and itssubsequent delivery to inhabitants . Other considerations critical considerations when locating carbonmonoxide detectors are areas with closed doors and rated demising walls, which can isolate or separateareas within HVAC zones. Additional information for the location of carbon monoxide detectors is availablein the Fire Protection Research Foundation (FPRF) technical report,“Development of a Technical Basis forCarbon Monoxide Detector Siting.”

Description Approved

image.jpgAdd the figure or similar as an example of possible design and risk considerations in typical build residential environment


The current verbiage mentions that CO may be circulated by HVAC systems, but does not mention any protection or detection from CO generated from the HVAC appliance or the HVAC system being the source itself. By adding this supplemental language to the section, optional methods of detection may be considered to protect against such hazards, above and beyond the code requirements. There is currently a large risk of CO exposure within most occupancies, and methods of detection such as within the supply airstream may prevent such occurrences.. See attached figure of a basic residential HVAC design. By placing CO detection in basements, outside small enclosed spaces, or in hallways, it is easy to see that there is little to no warning for occupants in the small areas and bedrooms, especially in inefficiently designed systems. By the HVAC design, the CO enriched warm air is efficiently delivered away from the detector adjacent to the furnace. This is not only a performance based design issue, as it is also simply an everyday typical construction and normal use issue. A similar figure(s) should also be considered for typical commercial, and commercial-residential applications where make-up and "fresh air" intakes, adjacent exhaust stacks, parking and staging area concerns also need to be considered.

B.1 Carbon Monoxide.


42 of 49 9/9/2016 9:56 AM

Carbon monoxide is an odorless, tasteless, colorless gas produced by incomplete combustion. Solid, liquid,or gaseous fuels can each, under certain conditions, produce lethal concentrations in the home. anyoccupiable space including but not limited to a home, business, hotel/motel, vacation rental, school,daycare, dormitory, healthcare facility, ice rink or boat/motorcraft. Not all public or private occupiablespaces are required by law to install carbon monoxide detection equipment (See Table B.1 and FigureB.1.) Personal portable carbon monoxide detectors should be used if sleeping in an environment where itis not clear if carbon monoxide detection equipment is present.

CAUTION: The values in Table B.1 are approximate values for healthy adults. Children, the elderly, andpersons with pre-existing physical conditions might be more susceptible to the effects of carbon monoxideexposure. Continued exposure after unconsciousness can cause death.

The dangers of carbon monoxide exposure depend on a number of variables, such as the occupant'shealth, activity level, time of exposure, and initial carboxyhemoglobin (COHb) level. Due to these variables,Table B.1 and Figure B.1 are to be used as general guidelines and might not appear quantitativelyconsistent.

The following equation for determining the estimated percent of COHb in the blood is from “A proposal forevaluating human exposure to carbon monoxide contamination in military vehicles,” by Steinberg andNielson and “Considerations for the physiological variables that determine the blood carboxyhemoglobinconcentration in man” by Coburn, Forster, and Kane:

[B.1]

where:

% COHb t = percentage of COHb at time t

% COHb0 = percentage of COHb in the blood at time 0

t = time (minutes)

B = 0.0404 (work effort)

ppm CO = parts per million carbon monoxide

Table B.1 Symptoms of Carbon Monoxide Exposure Based on Concentration

Concentration (ppmCO) Symptoms

50 No adverse effects with 8 hours of exposure

200 Mild headache after 2–3 hours of exposure

400 Headache and nausea after 1–2 hours of exposure

800Headache, nausea, and dizziness after 45 minutes of exposure; collapse andunconsciousness after 2 hours of exposure

1,000 Loss of consciousness after 1 hour of exposure

1,600 Headache, nausea, and dizziness after 20 minutes of exposure

3,200Headache, nausea, and dizziness after 5–10 minutes of exposure; collapse andunconsciousness after 30 minutes of exposure

6,400Headache and dizziness after 1–2 minutes of exposure; unconsciousness anddanger of death after 10–15 minutes of exposure

12,800 (1.28% byvolume)

Immediate physiological effects; unconsciousness and danger of death after 1–3minutes of exposure

To increase public awareness of the fact that not all carbon monoxide exposure risks occur in the home. The current laws (state by state and inconsistent) are not enough to protect consumers from possible injury and death due to carbon monoxide poisoning in public places (such as hotels, schools and dormitories) where they may observe smoke detection equipment (which is required) and be mistakenly led to believe carbon monoxide detection equipment is onsite as well.

My parents both died of carbon monoxide poisoning in a hotel room in North Carolina in 2013 due to malfunctioning pool heater and exhaust equipment (a case that hopefully the NFPA will review in its entirety as part of its standards processes). No carbon monoxide detectors were present anywhere in the hotel. Emergency responders and hotel staff thought either the smoke detector and/or the combustible gas detector was a CO detector. A boy and his mother were put into the room a few weeks later and the boy also died of carbon monoxide poisoning, his mother was permanently injured. My mother worked for a natural gas company for 30 years. My parents had CO detectors in every bedroom of their home. I cannot imagine two more unlikely people to die of CO poisoning -- anywhere. I'm sure they assumed, as most of us do, that hotels are required to have CO detectors. Only 12 states require CO detectors in hotels, none require them in every room. We see a smoke detector and an evacuation map posted in a hotel room and think steps are in place to protect us from known dangers such as CO poisoning. Carbon monoxide awareness campaigns are directed at homeowners. I've not seen one piece of public awareness literature that references the fact you could die from CO poisoning in a hotel room. Yet for decades dozens have people have died and thousands have been injured in hotels. There are also numerous cases of CO exposure in schools, restaurants, boats and other public places.
